PCB Assembly FAQ

We offer a full range of PCB assembly services, including Surface Mount Technology (SMT) assembly, Through-Hole (DIP) assembly, mixed-technology assembly, BGA/LGA/QFN fine-pitch assembly, prototype assembly, low-volume production, and high-volume mass production.

We can assemble surface mount components as small as 01005 package size, as well as fine-pitch components with a minimum pitch of 0.3mm, including BGA, LGA, QFN, and CSP packages.

The standard lead time for prototype PCB assembly is 3-5 business days; for low-volume production, the lead time is 5-10 business days; for high-volume mass production, the lead time ranges from 10-20 business days, depending on the order quantity and complexity.

We offer flexible MOQ options: for prototype assembly, the MOQ is 1 piece; for low-volume production, the MOQ starts from 10 pieces; for high-volume mass production, we can accommodate orders from 1000 pieces upwards.

We provide a full range of inspection and testing services, including Automated Optical Inspection (AOI), X-ray inspection for BGA/LGA components, In-Circuit Test (ICT), Functional Circuit Test (FCT), flying probe test, and visual inspection, ensuring 100% of assembled PCBs meet your quality standards.

Yes, our engineering team can provide comprehensive DFA recommendations for your PCB design, including component placement optimization, footprint verification, solder paste stencil design recommendations, thermal management optimization, and manufacturability improvements to reduce assembly costs and improve production yield.

There is no fixed limit on the number of components; we have experience assembling PCBs with over 1000 components, including both surface mount and through-hole components, for complex industrial and electronic applications.

Yes, we provide a full range of post-assembly services, including acrylic, silicone, and polyurethane conformal coating, epoxy potting, encapsulation, and waterproofing services, to protect your assembled PCBs from harsh environmental conditions.

Yes, all of our PCB assembly processes are fully RoHS-compliant, and we specialize in lead-free SMT and DIP assembly, using lead-free solder paste and materials that meet EU RoHS, REACH, and other international environmental standards.

We offer a 1-year warranty for all PCB assembly services, covering manufacturing defects, soldering issues, and component failures under normal use conditions. We also provide after-sales technical support, troubleshooting, and rework services for any assembly-related issues.

For standard SMT/PCB assembly, you need to provide:

• Bill of Materials (BOM) with complete part numbers, specifications, and quantities
• Pick and Place coordinate file for SMT components
• Silk screen (legend) drawing with component reference designators
• PCB Gerber files for stencil manufacturing and assembly verification

We support global logistics services including DHL, FedEx, UPS, TNT, and EMS for international shipments, as well as standard domestic logistics services.
Yes, we can help arrange professional freight forwarding services for both domestic and international shipments, including customs clearance and tax handling for international orders.
